ip igmp max-groups
ip igmp max-groups
Use the ip igmp max-groups interface configuration command on the switch stack or on a standalone
switch to set the maximum number of Internet Group Management Protocol (IGMP) groups that a
Layer 2 interface can join or to configure the IGMP throttling action when the maximum number of
entries is in the forwarding table. Use the no form of this command to set the maximum back to the
default, which is to have no maximum limit, or to return to the default throttling action, which is to drop
the report.
ip igmp max-groups {number | action {deny | replace}}

After the switch learns the maximum number of IGMP group entries on an interface, the default

the IGMP group to the interface.
